The British Army require UAS-deployable sensor technologies to survey river data for land force mobility and crossings.
An industry competition has opened with the aim of reducing risk to personnel using uncrewed and rapid multi site survey.
Agencies within the UK Ministry of Defence have launched an industry competition to deliver novel sensor technologies, deployed from uncrewed aerial systems (UAS), allowing the British Army to assess the battlespace.
In doing so, the Government aim to reduce the risk to personnel tasked with surveying sites in person.
The competition specifically addresses two areas: the ability to measure ground bearing capacity and underwater river profiling.
Historically, this so-called “wet gap” has always posed challenges to the pace of land force mobility and logistics. But it is hoped, given recent technological advancements in autonomy, that the defence industry may enable the Army to travel faster and overcome the human risk to conventional surveying.
In fact, the competition requires that operators conduct the mission at a range of ~3-5km for the final deployment.
“Increasing the pace, stealth and number of viable crossing sites will increase operational agility and obfuscate tactical intent,” read the competition document.
Each tender must deliver a demonstrable capability at technology readiness level six.
No more than £2m ($2.7m) will be made available for the competition, according to the notice issued on 6 May. UK Defence Innovation expects to fund three to four proposals across both challenges for a contract period of up to 15 months with plans to begin in October.
The submission deadline is scheduled to close midday on 16 June 2026.
Royal Engineer reconnaissance teams are tasked with assessing whether the ground and riverine environments are suitable for the safe passage of vehicles and whether specialist gap‑crossing equipment is required for the force.
Currently, measurements are taken in person.
An earlier competition took place in 2021 led by the Defence and Security Accelerator.
The competition demonstrated the potential for remote and autonomous systems in assessing the wet gap. However, each single uncrewed platform was limited in coverage, mobility and autonomy to deliver a full high fidelity wet gap survey.
In the 2021 competition, Nordic Unmanned was able to ascertain the water depth and flow speed using its ball-shaped WaFlow instrument but failed to demonstrate ground-measuring capabilities.
Ultimately, the trials exposed the penetration limits of bathymetric LiDAR in turbid conditions and revealed a need for robust UAS-deployable sensors to estimate ground bearing capacity across different sites.
A lot has changed in warfare since then. Recent conflict trends indicate a growing demand for uncrewed systems and intelligence, surveillance and reconnassance (ISR) capabilities.
In Ukraine, it is said that the fast-moving UAS sector – demonstrated by first-person view drones and fibre optic controlled systems – is changing on a daily basis.
In this backdrop, the data analytics firm GlobalData found that the emergence of novel technologies such as AI, LiDAR, and computer imaging are major drivers for investment in the remote sensing value chain.
The consultancy points to the growing integration of sonars, radars, and optronics on both civilian and military uncrewed vehicles, which are seeing increased use for hydrographic surveying, asset monitoring, environmental conservation, and even commercial shipping operations.
The Ministry of Defence likewise emphasised the need for modular, platform agnostic sensor packages that can be rapidly remounted when platforms fail or when missions require only part of the full survey.
